Les Invalides, commonly known as Hôtel national des Invalides, or also as Hôtel des Invalides, is a complex of buildings in the 7th arrondissement of Paris, France, containing museums and monuments, all relating to the military history of France, as well as a hospital and a retirement home for war veterans, the building’s original purpose. The buildings house the Musée de l’Armée, the military museum of the Army of France, the Musée des Plans-Reliefs, and the Musée d’Histoire Contemporaine, as well as the Dôme des Invalides, a large church with the burial site for some of France’s war heroes, most notably Napoleon Bonaparte.
n 1676 Jules Hardouin-Mansart was commissioned with the construction of a place of worship on the site. He designed a building which combined a royal chapel (now Dôme des Invalides) with a veterans’ chapel (now Cathedral of Saint-Louis des Invalides). In this way, the King and his soldiers could attend mass simultaneously, while entering the place of worship though different entrances, as prescribed by court etiquette. This separation was reinforced in the 19th century with the erection of the tomb of Napoleon I, the creation of the two separate altars and then with the construction of a glass wall between the two chapels.
